Description

Surface treatment agent and preparation method thereof, method for treating fiber product, and method for producing treated fiber product

The present invention relates to a surface treatment agent, and particularly to a water-repellent oil-repellent agent or an antifouling agent.

Conventionally, a fluorine-containing water-repellent oil-repellent agent made of a fluorine-containing compound is known. If this water- and oil-repellent agent is used to treat a substrate such as a fiber product, it will show good water- and oil-repellency.

Recent research results [EPA report "PRELIMINARY RISK ASSESSMENT OF THE DEVELOPMENTAL TOXICITY ASS ℃ IATED WITH EXPOSURE TO PERFLUORO ℃ TANOIC ACID AND ITS SALTS" (http://www.epa.gov/opptintr/pfoa/pfoara.pdf)] Etc., has clearly understood the environmental impact of PFOA (perfluorooctanoic acid), one of the long-chain fluoroalkyl compounds, and published a scientific investigation of PFOA on April 14, 2003.

On the other hand, Federal Register (FR Vol. 68, No. 73 / April 16, 2003 [FRL-2303-8], http://www.epa.gov/opptintr/pfoa/pfoafr.pdf), EPA Environmental News FOR RELEASE: MONDAY APRIL 14, 2003 EPA INTENSIFIES SCIENTIFIC INVESTIGATION OF A CHEMICAL PROCSSING AID (http://www.epa.gov/opptintr/pfoa/pfoaprs.pdf) and EPA OPPT FACT SHEET April 14, 2003 (http: //www.epa.gov/opptintr/pfoa/pfoafacts.pdf), has disclosed the possibility of small polymers (telomer) to generate PFOA through decomposition or metabolism (small high score refers to long chain fluoroalkyl). In addition, small polymers are also disclosed for use in a variety of products such as foam fire extinguishing agents, beauty products, cleaning products, carpets, textiles, paper, leather, and the like that impart water and oil repellency and stain resistance. There is concern that fluorinated compounds will accumulate in the environment.

In addition, the fluorine-containing water- and oil-repellent agent exhibits water- and oil-repellency, and must be heat-treated at a high temperature (for example, 100 ° C. or higher) after being adhered to a base material such as a fiber product. Heat treatment at high temperatures requires high energy.

Japanese Patent Application Laid-Open No. 2006-328624 discloses a water-repellent agent which is a non-fluorine-based polymer containing a (meth) acrylic acid ester having a carbon number of 12 or more as a monomer unit, in which, The proportion of the (meth) acrylic acid ester is 80 to 100% by mass of the water-repellent agent relative to the total amount of the monomer units constituting the non-fluorine-based polymer.

However, this water-repellent agent is poor in water and oil repellency.

In addition, the present invention provides a surface treatment agent for an aqueous emulsion, which comprises (1) a copolymer, a first polymer formed from a first monomer, and a second polymer formed from a second monomer. Of these, the second polymer is a polymer in the presence of the first polymer, and the first single system contains (a) a long-chain acrylate monomer represented by the formula: CH ₂ = CA ¹¹ -C (= O) -OA ¹²

[In the formula, A ¹¹ is a hydrogen atom, a monovalent organic group or a halogen atom, and A ¹² is a linear or branched hydrocarbon group having 18 to 30 carbon atoms. ], The first single system does not contain (b) a halogenated olefin monomer, and the second single system contains (b) a copolymer of a halogenated olefin monomer: (2) a surfactant containing a nonionic surfactant, and (3) Liquid medium containing water.
